[meta-freescale] [IMX6Q Sabre Lite, Linux 3.4.34] Booting is failed in calibrate_delay_converge().

Hi, Eric,

Thank you for the hint.

Yes. I can see the message.

Also, when I using the kernel 3.0.35-gb0b02db-dirty,
the debug message shows "CPU identified as i.MX6Q, silicon rev 1.2".

But, in 3.4.34 kernel, I couldn't find the mesage.

Is there any initalization code for "i.MX6Q, silicon rev 1.2".

Thanks again.
Best Regards,
Shinkyu.
